django-generic-confirmation
Django-generic-confirmation makes it easy for developers to add forms to a webapplication where the submitted data should only be used after an out-of-band confirmation was done. For example if a user wants to change his email address, generic-confirmation will make it really easy for the developer to add an out-of-band confirmation process (sending an email with a random link to the user) before saving the new email address to the database.
The core of django-generic-confirmation is fully unit-tested and the app is in use at a few real-world projects confirming email addresses and mobile phone numbers. Feel free to read about the usage in docs/usage.txt or on http://django-generic-confirmation.readthedocs.org.
django-generic-confirmation 0.4.x is compatible with Django 1.8 - 1.11.
